Chemistry of the Great Big Blue: A Pesticide Mystery

Posted on By Bluegrass Blue Crab
Uncategorized

As part of my ongoing community-based research on water quality in coastal North Carolina, I ended up tasked with answering what I thought would be  a very basic question: what is the predominant pesticide used in my county? The largest farm and by far the largest amount of cropland is occupied by a traditional corn/soy rotation with the occasional cotton thrown in. Given the multitude of American acres donated to corn/soy, I figured I could easily find out the basics of that crop’s chemistry. Not so. My little information adventure has made me realize why there are so many rumors surrounding farming’s impact on water quality in the region. Rumors are easier to find than facts.

False Fish, Pink Slime, and Dactylopius frappucoccus: food supply, food choices, and establishing a personal food ethic

One solution, though not everyone can raise their own chickens.
A significant source of food for me. Of course not everyone can raise their own chickens.

Food is a tricky. For some people, food choice is an essential component of cultural heritage and national identity. For others, food choice is a statement of philosophical or moral principles. For many, being able to reject food is an unobtainable luxury. One thing is certain: food is so central to the human experience that when we question our food choices, when we are forced (or force others) to change them, when we discover that the choices we make are not what we think they are, it is impossible to separate our food ethics from our social structure. Which is why seemingly trivial revelations–bugs in your coffee, meat made slime, or a fish by any other name–often result in major outrage and structural changes. Eating is simultaneously a deeply personal experience and one in which, for much of the developed world, we are completely detached from the source.

Personal Sustainability Challenge May Edition – ditching the disposable razors

A rigorous documentation of 24 hours of neck-beard growth, highlighting both the coarseness and density of neck-beard hairs.

I am what most people would consider a “well-bearded” individual. According to this graph, I fall rather appropriately into the category of “Sea Captain”. Despite my proud embeardedness, I also play host to a horrifying parasite frequently referred to as a “neck beard”–a foul nest of bristles with a coarseness and consistency that lies somewhere between steel wool and dermal denticles. This means that, appearances aside, I still need to shave, sometimes twice, daily.

If you’re like most American men, this means using either disposable razors or cartridge razors, both of which result in discarded plastic and steel. Cartridge razors, commonly found with an increasingly horrifying numbers of blades, vibrators, laser pointers, and PEZ dispensers, produce less waste but are also more expensive. The average price for the three-bladed monster at my local pharmacy runs about $4.00 a cartridge, and those things don’t last very long–I’m lucky if I can get 2 weeks out of a single cartridge, often less (although, somehow, the very last cartridge in each pack seems to last 3 times longer than the others). In addition to wasting plastic and steel in the actual cartridges, and plastic and cardboard in the packaging, I’m burning around $100 per year.

There are a few possible ways to reduce shaving associated waste. The most obvious is switching to an electric razor–which is what our other beardly blogger did until recently (he now reports that “My beard used to destroy electrics in less than a year.“)–but the cutting heads need to be replaced and they will, eventually wear out. I’m also not a fan of electric razors, I don’t particularly like the shave I get with them. Next on the list are single-blade safety razors, the classic standard of the 1930’s through 80’s. These have the advantage of no plastic, and allegedly get you a closer, cleaner shave than disposables (though I suspect that has more to do with the brush/lather and spending more time on getting a good shave), but the blades are still disposable. So, it appears as though, if I truly want to eliminate as much waste as possible from my shaving routine, I need to take a more traditional approach.

Aquaculture in NC: Carolina Mariculture Co.

Though oyster mariculture isn’t new to places like the Chesapeake Bay, Jay Styron’s Carolina Mariculture Company, based in Cedar Island, NC, is a shining vision of the future in North Carolina. Much of the state’s efforts in aquaculture are directed at tilapia, catfish, and hybrid striped bass, which are grown in ponds on traditional farm land. These are often grown as a means of diversifying an existing farm economy. Mariculture, though, blends this type of aquaculture with commercial fishing to grow seafood in estuaries and inshore regions, creating a saltier crop. In many ways mariculture should be embraced by both farming and fishing communities but is often instead viewed as the strange uncle of the food production family. Enter pioneer Jay Styron, who grows oysters not only for food but also demonstration purposes – and he proudly creates delicious oysters.

Towards a personal stewardship ethic – monthly sustainability challenge

Posted on By Andrew Thaler 4 Comments on Towards a personal stewardship ethic – monthly sustainability challenge
Uncategorized

We tend towards waste. As a nation, as a community, and in our personal lives, waste is ubiquitous and often imperceptible. That we can afford to discard is an unfortunate side effect of having a high quality of life. Waste is not always a bad thing, either. We’re comforted by the fact that our doctors use disposable needles, that food can be packaged and preserved, that soiled diapers can be discarded. Disposability is freedom from the tedious chores of our grandparents and great-grandparents. It is access to time that can be spent with our loved ones or engaged in more fruitful pursuits. But there is still plenty of unnecessary waste that exists purely for convenience.

Those of us who consider ourselves environmentalist, good stewards of the earth, are often just as guilty of waste, myself included. Over the next several months, I will be exploring ways to reduce my own waste production. Each month I will identify some aspect of my personal life that generates unnecessary waste and explore solutions. Plastic is my major target, but I will also be looking for other resources drains that could be made more efficient (or, if possible, eliminated).
